Eachof the projections 4 2 by means of an attaching member 3 assembled has atwistable portion 20 forming an extension with the condenser canadjacent its lower end of the spacing portion l1 and adapted to projectand providing a plurality of projecting portions through an opening I ofthe mounting plate.

4 extending beyond the lower end of the can Each of the twistableportions 20 has a pair of and through the plate 2 and providing meansenelongated support-engaging elements or lugs 2| gaging the rear face 5thereof (Fig. 3). The integral with opposed sides of the projectingmounting plate 2, which may be of metal or portion and disposed normallyin the plane of plastic material, has a central opening 6 and a theprojecting portion. Each of the lugs 2i has 05 plurality of narrowopenings 1 disposed around one end integrally joined to the twistableportion and its opposite end free and in normal position in adjacentrelation to the spacing portion II.

Attachment of the condenser can I to the mounting plate 2 is quickly andeasily accomplished by moving the projecting portions 4 through theapertures 1 until the shoulders l8 engage the upper surface IQ of themounting plate adjacent the apertures 1. Next the portions 20 of theprojecting portions 4 extending beyond the rear face 5 of the mountingplate are twisted by a suitable tool (not shown) to move the lugs 2i outof the normal plane of the projecting portions to engage tightly behindthe surface 5. One of the features of my invention is embodied in theparticular dimensions of portions of the attaching member wherein thenormal length I of the lugs 2| is greater than the distance between thepoints of junction of the lugs with the portions 20 and the rear face 5of the mounting plate when the projections 4 extend through the openings1 and before twisting. As a result of.

these relative dimensions of the parts, the lugs are bowed aftertwisting of the portions 20 so as to take up variations in thickness ofthe mounting plate 3 and at the same time draw the condenser can tightlyagainst the mounting plate 2.

The soldering terminals II have a relatively straight flat body portion22. Attaching means in the form of a flange or foot portion 23integrally joined to one end of the body portion extends inright-angular relation to the normal plane of the body portion. The footportion 22 is adapted to be held between the insulating plates l3 and H,as most clearly shown in Fig. 3, so as to maintain the terminal inassembly with the condenser can and in upright position. A pair ofspaced wing portions 24 integrally joined to opposed side edges of thebody portion extend out of the normal plane of the body portion. Thewing portions 24 are adapted to be bent to embrace a connecting lead(not shown) between the foil of the condenser and the soldering terminalprior to soldering the connecting lead permanently to the body of theterminal. The connecting leads are adapted to extend from the foil ofthe condenser through openings (not shown) in the insulating plates l3and i4 into said soldered engagement with the terminals ll. Integralwith the opposite end of the body portion 22 from the foot portion 23 Ihave provided an outwardly-extending wire-supporting means or lipportion 25. The lip portion extends be yond one side of the body portion22 and has a lower open face 26 adapted to support the bare wires 21 ofthe leads 28 (Fig. 7) so that'the bare wires may be soldered thereto.

Although I have set out the preferred use of my improved attachingmember in connection with an electrolytic condenser, it is understoodthat the part may be used in combination with units of manufacture ofother shapes and forms. Furthermore, I perceive that projecting portionsI embodying one or more features of my present invention might be formedintegrally with the lower end of the condenser can i so as to effect asatisfactory attaching means for securing the unit to a panel.

Although I have illustrated and described a preferred embodiment of myinvention, I do not wish to be limited thereby because the scope of myinvention is best set out in the following claims.

I claim:

1. Incombination, a support, a part to be secured to said support andattaching means for securing said part to said support, said attachingmeans comprising projecting portions extending beyond the outermostmargins of an end of said part, each of said projecting portion: passingthrough an opening in said support and having integral lug-shapedsupport-engaging elements adjacent its opposite edges and normally inthe plane of said projection, said elements having free end portionsfacing said. end of said part and spaced therefrom, and said projectionsbeing twisted on the opposite side of said'support from said part todispose said support-engaging elements behind said support.

2. In combination, a support, a part to be secured to said support andan attaching member for said part, said attaching member comprising abase portion secured adjacent an end of said part and projectingportions extending from said base portion beyond the outermost marginsof said end, each of said projecting portions having a twistable portionpassing through an opening in said support to a position beyond thelower surface thereof and having integral lug-shaped support-engagingelements adjacent its opposite edges and normally in the plane of saidprojection, said elements being joined at one end to said twistableportion and having a-free end at its opposite end facing said base andspaced therefrom, the length of said support-engaging elements beinggreater than the distance between the points of junction of saidelements with said twistable portion and said lower surface of saidsupport, and said twistable portions being twisted to dispose saidsupport-engaging elements behind said support, and said elements beingbowed by said twisting action.

3. In combination; a support. a part to be secured to said support andattaching means for securing said part to said support, said attachingmeans including a projecting portion extending beyond outermost marginsof anend of said part, said projecting portion passing through anopening in said support and having an integral bendable lug-shapedsupport-engaging element ad jacent one edge and normally in the plane ofsaid projection, said element having a free end portion facing said endof said part and spaced therefrom, and said projection being twisted onthe opposite side of said support from said part to dispose saidsupport-engaging element behind said support whereby the said elementmay ad just itself to the thickness of said support by bending relativeto the, rest of said projection.
